3x9 - Ӕon Flux

The episode opens with Æon chasing Bambara, a vicious man who frequently causes injury or death to those he encounters. Æon, ignoring his victims, pursues him through a train and onto a building site. Bambara escapes Æon killing a construction worker in the process but is captured by Trevor Goodchild. He inserts a strange robot into Bambara through the man's navel and he suddenly loses his darker side, becoming friendly to those around him and quickly befriending an orphan. Trevor says the robot is a 'Custodian', an artificial conscience of his creation which he hopes to implant in all citizens. Æon then meets up with an organization of women who are opposed to Trevor's project who are planning to remove the implanted Custodians and bring the operation to an end. Æon goes after Bambara's Custodian ....
